12 A unit configuration file whose name ends in .target encodes
13 information about a target unit of systemd, which is used for grouping
14 units and as well-known synchronization points during start-up.
15
16 This unit type has no specific options. See systemd.unit(5) for the
17 common options of all unit configuration files. The common
18 configuration items are configured in the generic [Unit] and [Install]
19 sections. A separate [Target] section does not exist, since no
20 target-specific options may be configured.
21
22 Target units do not offer any additional functionality on top of the
23 generic functionality provided by units. They exist merely to group
24 units via dependencies (useful as boot targets), and to establish
25 standardized names for synchronization points used in dependencies
26 between units. Among other things, target units are a more flexible
27 replacement for SysV runlevels in the classic SysV init system. (And
28 for compatibility reasons special target units such as runlevel3.target
29 exist which are used by the SysV runlevel compatibility code in
30 systemd. See systemd.special(7) for details).
31
32 Unless DefaultDependencies= is set to false, target units will
33 implicitly complement all configured dependencies of type Wants=,
34 Requires=, RequiresOverridable= with dependencies of type After=.
